GEORGE F. DIDKSON, O13 CHICAGO, ILLINOIS, ASSIGNOR T0 CONFECTIONERS ANDSUPPLY (70., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CAN-WASHING MACHINE.

Specification of Letters Patent.

Patented Oct. 1, 1912 Application filed April 17,1911. Serial No.621,438.

To all whom 'it may concern: v

Be it known that I, Gnome F. Dickson,

a citizen of the United States of America,

and a resident of Chicago, in the county of Cook, State of Illinois,have invented cer tain new and useful Improvements in Can- /VashingMachines, of which the following is a specification.

This invention relates to that type of apparatus for washing milk cansand the like, in which a revolving brush mounted horizontally above thewater tank and having provisions whereby a supply of water iscontinually ted to the brush in the practical use of the apparatus. Andthe present improvement has for its object to provide a simple andeilicient structural formation and combination ot' 'parts in a combinedvcan Washing, rinsing and sterilizing apparatus, whereby the wash wateris constantly and uniformly supplied to the revolving brush during theoperation of the apparatus, and with which the desired temperatureduring the diilerent stages of the operation is readily and efficientlycontrolled and regulated, all as will hereinafter more fully appear.

In the accompanying drawingsz-liguro 1, is a side elevation, with partsin section, of an apparatus embodying the present. invention. Fig. 2, isan end elevation. Fig. 3, is a detail plan view of an end of theapparatus. Fig. 4, is an enlarged detail section, on line m--zc,'Fig. 1,of the 'revolu ble brush head. Fig. 5, is an end elevation of the same,with the tubular carrying shaft in section.

' Similar numerals of reference indicate like parts in the severalviews.

Referring to the drawings, 1 represents a horizontal water trough ortub, of the usual open top construction, provided with legs 2 by whichit is supported above the "floor.

3 is a hood arranged above an end portion of the tub l, and formed witha closed end head having adjacent relation to an end head of the tub 1,and constituting a vertical extension of the same. Said hood is adaptedto encompass the hereinafter described revolving brush and its forwardend is open to permit the ready introduction of the milk can or vesselinto position for washing. v

1 1s a standard arranged centrally at one end 0% the tub 1, and providedwith a l ugitudinal bearing box 5, at top for the tubular shaft of therevoluble brush hereinafter described 6 is the longitudinal brushcarrying shaft above referred to. Said shaft is journaled in the box 5aforesaid, with its forward brush carrying end extending into theinclosure formed by the hood 3 aforesaid and the adjacent portion of thetub 1. At its rear end said shaft projects beyond the box 5 for theattachment of the driving pulley 7 and other connections hereinafterdescribed.

8 is a brush carrying head secured to the forward end of the shaft 6,and comprising an end attaching hub 9, and a rectangular closed skirtport-ion 10 provided with miterflanges 11 at its corners that formchannels for holding by their backs the series of brush sections now tobe described.

12 are a series of counterpart brush sections, each one of whichcomprises an elongated straight portion the back of which fits one ofthe channels aforesaid and is secured therein by screws or other usualfastening means, and a curved portion 13 formed as an extension of saidstraight portion and which projects toward a similar curved portion ofan opposed brush section,

to provide the brush as a whole with a rounded front end as illustratedin Figs. 1

'and 4. With the described construction,

with a can in lace over the brush, and the wash water owing through thetubular shaft 6, the water passes out of the open end of the same,through the rounded forward end of the brush and against the bottom ofthe can bein washed. The water then passes backward between the sides ofthe can and the brush bristles, as well as through the longitudinalchannels between the brush sections, to carry the impurities detached bythe brush in its revolution out of the ca1-."...nd into the trough ortub 1.

14 is a chain wheel carried by the shaft 6, and connected by a chainbelt 15 with a simi lar wheel on the operating shaft of the rotarycirculating pump hereinafter described.

16 is a non-rotary gland in which one end of the shaft 6 turns in awater tight manner, and said gland in turn is connected by pipeconnection 17 with the outlet end of the before mentioned circulatingpump.

18 is the circulating pump above referred to, and which is attached tothe above do- 1 and 2.

scribed standard if. Said circulating pum i lowing operations orfunctions can be oonis preferably of the rotary type, with its operatingshaftcarrying a chain wheel 19 operagively engaged by the chain belt 15,aforesai 20 is the supplypipe of the pump 18. In the presentconstruction said pipe is of an inverted U shape and spans an end wallof the tub or trough 1, with one leg extending into the tub I, to nearthe bottom of the same, While the other leg is connected to the inletend of the pump 18, as shown in Figs.

21 is a vertical drain pipe arranged in the interior of the tub I formaintaining a predetermined height of the wash water within said tub. v

22 is an open top'horizontal tray attached to the end of the tub 1,opposite the hood 3, and having drainage connection with the interior ofsaid tub by -a drain opening 23 in an end wall of said tub.

241 is a vertical nozzle, provided with the usual supporting spider 25,and arranged centrally in the tray 22. Said nozzle and spider areadapted to receive an inverted milk can or the like in the final rinsingand steaming operation on the same.

26 is a hollow supply head arranged beneath the tray 22 and havingcommunication with the nozzle 24 aforesaid.

27 is a water supply pipe connected to the head 26, and provided with acontrolling valve 28. 29 is a steam supply pipe con-- nection to theother end of the head 26, aforesaid, and provided with a controllingvalve 30.

31 is a branch pipe extending from the steam supply pipe 29 to the lowerportion of the tub I and adapted to introduce a supply of water or ofsteam into said tub in the reg ulation of the temperature of thecontents of the tub. Said branch pipe is provided with a controllingvalve 82.

"With the above described arrangement of steam and Water supplyCOIInefitirms the Folveniently attained :By closing the valves 30 and32, and opening the valve 28, water alone is delivered to and dischargedfrom. the nozzle 24. By opening the valves 28 and 30, and closing thevalve 32, water and steam are delivered to and discharged from thenozzle By closing the valves 28 and 32, and opening the valve 30, stea1n alone is delivered to and discharged through the nozzle 24-. Byopening the valves 28ff1 d 32 and closing the valve 30 Water i5 suppliedthrough the branch plpe 31 to the tub or trough l, as well as to thenozzle 24. By closing the valve 28, and opening the valve 30 and 82,steam alone is supplied to the wash water in the tub I to heat the same,and also to the nozzle. v

Having thus fully described my said invention what I claim as new anddesire to secure by Letters Patent, is

, A can washing machine comprising in combination, an open top trough, arevoluble fountain brush disposed horizontally above said trough, ahollow shaft carrying said brush, a fixed supporting standard disposedat one end of Said trough, a bearing box on the upper end of thestandard providing a journal support for the hollow shaft'aforesaid, apump mounted on said standard and having an operating shaft disposed inparallel relation to the aforesaid hollow shaft,

operative connections between said shafts, a pipe connecting the inletend of said pump with the interior of the trough, a pipe connecting theoutlet end of said pump to the hollow shaft at the rear of the operativeeon nections aforesaid, and means for imparting rotation to the hollowshaft, substantially as set forth.

Signed at Chicago, Illinois, this of April 1911.
